| Use advice for data set | Users of this dataset should note that the functional unit is defined as the use performance of 1 tonne of 42.5 ordinary Portland cement. The system boundary for this LCA data is confined to the direct production process within the cement plant, which includes raw material entry, pretreatment, grinding of raw meal, calcination of raw meal, clinker grinding, until cement homogenization and storage. It does not account for upstream processes like raw material extraction, processing, or transportation. The geographical scope of this study is limited to the Beijing area, and users should be cautious when extrapolating this data to other regions or different production settings. |
| Technical purpose of product or process | The ordinary Portland cement with a strength grade of 42.5MPa described in this dataset is typically used in construction applications such as the building of infrastructure, residential and commercial structures. Its high strength makes it suitable for concrete components like beams, slabs, and columns that require significant load-bearing capacity. This dataset specifically accounts for environmental impact when incorporating waste incineration into the cement production process. |

| Model description | Functional unit definition: Take the performance of 1t 42.5 ordinary Portland cement as a functional unit. The system boundary is: from the entry of raw materials, raw material pretreatment, raw meal grinding, raw meal calcination, clinker grinding, until cement homogenization and storage, that is, the direct production process of cement in the entire cement plant, excluding raw material mining, Processing and transportation process. The geographical scope of the study is the Beijing area. |
